The type VI a tank locomotives of the Grand Ducal Baden State Railways were procured in 1900. Due to their unfavorable construction, no further procurement of this type took place.
history
As part of the testing of new designs of tank locomotives, the Maschinenbau-Gesellschaft Karlsruhe delivered two locomotives with a 1C wheel arrangement in 1900 . The locomotives with a large friction mass had sufficient tractive power and, thanks to the leading Adam's axle, good running properties when moving forward. When reversing, however, the locomotive was poorly guided and the superstructure was more stressed. The driving wheel diameter of 1480 mm enabled a speed of 70 km / h. This was too little for fast passenger traffic. The construction of the water boxes, which were extended to the height of the middle of the chimney, was not repeated in later tank locomotive types.
Since other types of tank locomotives (including the Badische VI b ) have been developed in the meantime, this unsuccessful design will not be continued. After the First World War, the two locomotives were given to the Réseau ferroviaire d'Alsace-Lorraine as reparations in 1919 . There they were retired until 1923.
Constructive features
The locomotives had an internal sheet metal frame. The smooth long bowl consisted of two shots. The steam dome sat on the foremost boiler section. The standing kettle had a pop safety valve.
The two-cylinder wet steam engine was arranged horizontally on the outside and worked on the second coupling axis. The cross head was guided in two rails. The coupling wheels were cushioned by leaf springs below. The barrel axle was designed as an Adam's axle and suspended over the axle with leaf springs.
The Westinghouse air brakes worked on all coupling wheels from the front. The sandpit was on the rear boiler section and sanded the center axis from the front. The coal container was on the rear wall of the driver's cab and the water container on both sides of the boiler up to the level of the smoke chamber.
